Long-Term Marijuana Use May Reduce Blood Flow To Hippocampus And Increase Susceptibility For Alzheimer’s, Study Indicates.

According to Medical Daily (11/28, Borreli), “long-term marijuana use may reduce blood flow to the brain, specifically the hippocampus, and increase the susceptibility for Alzheimer’s disease,” researchers found by using single photon emission computed tomography to help gain data from “approximately 1,000 current or former marijuana users and about 100 healthy participants” while “at rest and during a mental concentration task.” The findings were published online Nov. 24 in the Journal of Alzheimer’s Disease.
